3. An amusement park charges $6 to enter, and $3 per game. If you paid a
total of $18, how many games did you play?

You played 4 games

Step-by-step explanation:

You start with $18 and subtract 6 from the entry fee. Then, you divide the 12 you got from that and divide it by 3

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
